Targetoid hemosiderotic hemangioma is an uncommon, vascular, benign solitary lesion of lymphatic origin that can be misdiagnosed as other tumors including melanomas.
To evaluate the dermoscopic features of a large series of targetoid hemosiderotic hemangiomas.
Digital dermoscopic images of 35 histopathologically confirmed cases of targetoid hemosiderotic hemangiomas collected from 7 hospitals in Spain and Italy were evaluated for the presence of dermoscopic structures and patterns.
The results of our study reveal that the presence of central red and dark lacunae and a peripheral circular reddish-violaceous homogeneous area is the most common dermoscopic pattern in targetoid hemosiderotic hemangioma (71.4%). The targetoid hemosiderotic hemangiomas of our study were correctly diagnosed in 77% of cases.
Dermoscopy is helpful in improving the diagnosis of targetoid hemosiderotic hemangioma. However, attention must be paid to those cases that dermoscopically may show nontargetoid patterns, which often mimic other lesions, including melanoma.
靶样含铁血黄素性血管瘤是一种罕见的、起源于淋巴管的血管性良性孤立性病变，可被误诊为包括黑色素瘤在内的其他肿瘤。
评估大量靶样含铁血黄素性血管瘤的皮肤镜特征。
对从西班牙和意大利7家医院收集的35例经组织病理学确诊的靶样含铁血黄素性血管瘤的数字皮肤镜图像进行评估，以确定是否存在皮肤镜结构和模式。
我们的研究结果显示，中央红色和深色腔隙以及周边圆形红紫色均匀区域的存在是靶样含铁血黄素性血管瘤最常见的皮肤镜模式（71.4%）。我们研究中的靶样含铁血黄素性血管瘤在77%的病例中得到了正确诊断。
皮肤镜有助于提高靶样含铁血黄素性血管瘤的诊断。然而，对于那些皮肤镜下可能显示非靶样模式的病例必须予以关注，这些模式常模仿其他病变，包括黑色素瘤。
